INKER FOR RUBBER-STAMP PADS.

SPECIFICATION forming part of Letters Patent No. 446,889, dated February 24, 1891.

Application filed April 11, 1890. Serial No. 347,485. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE JAMES BEL- LAMY RODWELL, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented a certain new and Improved Inker forRubber-Stamp Pads, of which the following is a specification.

The object of the invention is to design a combined ink reservoir and spreader for applying ink onto pads used in connection with rubber stamps; and it consists, essentially, of a can having a small hole or holes made in its stopper, around which hole or holes apiece of felt or other porous material is placed in such a position that it projects above the end of the stopper, yet leaving a free passage for the ink through the hole or holes.

Figure 1 is a perspective view of my improved pad-inker, with the cap removed. Fig. 2 is a sectional elevation of same. Fig. 3 is a detail of the cap.

Pads used in connection with rubberstamps are sometimes made what are termed selfinking, in which construction the ink is placed below the porous pad and simply soaks through the top surface. These pads soon become hard and worthless. Other pads are inked by pouring the ink on the surface of the pad and smearing it over by means of a brush or rag. In this latter process of inking the fingers of the party preparing the pad are apt to be and usually are soiled with the ink, as it is difiticult to remove the cork from the bottle, pour the ink on the pad, and smear it over the surface .of the pad without soiling the fingers.

By the adoption of my inker all danger of soiling the fingers is avoided.

A represents a metal can, and B its stopper, through which a small hole a is made. The top of the stopper 13 is recessed to receive a ring 0, made of felt or other porous material. This ring project-s slightly above the top of the stopper B, so that the metal portion of the top of the stopper B will not come in contact with the pad when the ring 0 is rubbed over it.

When I use but one hole a in the stopper B, it is necessary to provide a spring-bottom for the can A, such as is used in ordinary squirt-cans; but when a large hole or a series of small holes is made the spring-bottom may be dispensed with.

In order to use myinker, it is merely necessary to upset the can A, and by pressing on the spring-bottom of the said can the ink is squirted out onto the pad, only a small quantitybeing thus deposited. The ring 0, of felt or other porous material, is then rubbed over the surface of the pad, so as to thoroughly (listribute the ink over the said surface. \Vhen the surface of the pad has been thoroughly and properly inked, the can is replaced on its bottom, when of course the ink will cease to run out and the cap D maybe fitted over the stopper B.

From this description it will be seen that the pad may be reinked as often as necessary without any danger of soiling the hands, and that as the felt does not-cover the holes the ink may be freely forced through the same, whereas if the felt covered the holes, as has been proposed in a somewhat similar device used for dampening labels, the ink cannot pass so freely through the holes, and it would, therefore, take a long time to saturate a large pad.

\Vhat I claim as my invention is 1. An ink-can provided with a stopper having a hole through it and an annular groove in its top, and a ring of felt or other porous material set into the groove in said stopper, arranged to leave the hole uncovered, substantially as and for the purpose specified.

2. An ink-can having a spring-bottom and provided with a stopper having a hole through itand an annular groove in its top, and a ring of felt or other porous material set into the groove in said stopper, arranged to leave the hole uncovered, substantially as. and for the purpose specified.
